杭州铸造厂炉顶开出式1.5吨电弧炉的电极夹持器及导电系统,1971年以前,由于结构不良,经常发生电极夹不住、夹持处冒火花、冷却水的下降水管烧红和烧断等现象;导电系统与起落架非带电部份间放电,引起绝缘击穿或导电铜管被烧穿、漏水等现象,严重影响了正常生产。后来,进行了如左下图所示的改革。 Hangzhou casting foundry top out of 1.5 tons EAF electrode holder and conductive system, before 1971, due to poor structure, the electrode often can not clamp, clamping Department sparks, cooling water pipe down red and red Blown and other phenomena; discharge between the conductive system and the undercarriage uncharged parts, resulting in insulation breakdown or conductive brass is burned through, leakage and other phenomena, seriously affecting the normal production. Later, the reform shown in the lower left figure was carried out.
